6 Claims. This invention relates to improvements in safes, particularly those which are used largely for the guarding of cmrency, bonds or other valuable securities, and has particular reference tents other than by use of the normal unlocking mechanism will result in the mutilation of the contents of the safe by staining or defacing such contents with a distinctively colored dye or other defacing agency, whereby the currency or other valuable papers are rendered unusable and/or unsalable, except for redemption or exchange.

The objects of the present invention are:

To provide means whereby entrance to the safe by destruction of the look by force, or an attack upon the safe by drilling or the use of destructive force, will cause the contents of the safe to be stained or otherwise defaced through the medium of a staining or defacing medium.

To provide means whereby removal and transportation of the safe as by unauthorized parties would cause the contents thereof to be damaged and rendered unusable.

The means by which the foregoing and other objects are accomplished and the manner of their accomplishment will readily be understood from the following specification on reference to the accompanying drawing, in which:

Fig. 1 is a sectional elevation of my safe taken on the center line.

Fig. 2 is a sectional plan taken as on the line II II of Fig. 1..

Referring now to the drawing the safe includes an inner chamber 10, a surrounding chamber 11, and a door which may be opened to provide access to the inner chamber 10, which door is preferably a removable plug 12. b I

The shells of the inner and surroundingchambers may be of integral construction, but I prefer to use built up structures in which the outer wall of the inner chamber comprises a hollow cylinder 13, preferably of hardened steel, a disc. shaped bottom 14 and an opposed disc shaped top 15, the discsbeing annularly channeledto re.-

. .ceive, respectively, the bottom and top ends of the cylinder 13, and being clamped together by a plurality of bolts 16, which secure and seal the shell 13, the bottom 14 and the top 15 hermeti: cally together.

The outer chamber likewise comprises a hollow cylinder 17, spaced from the cylinder 13 and substantially concentric therewith, a disc shaped bottom 18, preferably having a surrounding downwardly flanged rim 19 forming a base and a disc shaped top 20, which top and bottom are annularly channeled to receive respectively the lower and upper ends of the shell 17. The two discs are clamped together as by bolts 21' which secure and hermetically seal them to the shell. An exterior cylindrical casing 22 of thinner material may be used to encase the bolts 21, and give a finished appearance. The chamber 11 sur-' rounding the shell of the inner chamber is adapted to be filled with air under pressure, and is filled through the pipe 28, the pressure carried being shown on the gage 24. V

The upper discs 15 and 28 are centrally apertured and are connected together by a cylindrical neck 25 which is suitably bored out to receive the plug 12. Preferably the structure formed by the discs 15 and 20 and the neck 25 is an integral steel casting.

Disposed within the inner chamber, .and preferably concentric therewith, is a liquid container 26 of generally spherical shape having its upper portion open and surrounded by an integral cylindrical neck 27. Depending fromthe disc 15 is a flanged member 28, which is secured to the disc preferably by screws 29, and to the cylindrical neck 27 as by welding, whereby the liquid container 26 is rigidly supported. I

Mounted within the liquid container 26' is a spherically shaped money chamber 30,which pivotally supported by trunnions 31, these trunnions being mounted on adjustable pins 32 which pass through the outer wall of the. container 26. 33 is a counterweight which insures tipping of the money chamber when released. 34 is a latch arm secured to the chamber which latch I arm is engaged and held by a latch member 35. The disc 15 is provided with an aperture 36, which is tapped to receive the hollow shank 3'7 of a fitting 35, within which is carried a collapsible metal bellows 3 9, theinterior of which is in coinmunication,'through the shank 37, with he ai n the chamb 1 T le h 35 is pin connected to' the lower end of the fit-- ting 38, and is connected by a link 4c with the metal bellows 39, whereby, underthe pressure of the. air within the chamber 11, it is held in engagement withthe latch arm 34. 41 is a tension spring which disengages the latch member 35 on lowering of the air pressure within the chamber 11. r

42 is a hollow fusible plug, which communicates through a passageway 43 with the interior of the plug 12, whereby should heat be applied to burn off the combination knob 44, pressure of the air in thechamber 11 would be released and the'bellows [39 be allowed to collapse, accomplishing the release of the latch'arm as before.

The plug ,12preferably has its lower portion hollowed out to receive an annular fragile con-,- tainer 45, preferably of glass. 46 is a pin secured to and turned by'the knob 44 which pin extends through the container 45 into a locking mem: ber 47 which may be of any usual or well known form, and which member carries locking pins 48 which are projected to engage the lower portion of the plug 12 with the neck 25, or retracted to disengage them and allow removal of the plug. The detail of such locking parts not being a part i the present invention and therefore not being shown. Disposed above and resting on the member 47, is a plate '49 having upwardly projecting points 50. 51, 51 are light compression springs on which the fragile container rests and which support the container just clear of the points 50. Disposed above and resting on the fragile container 45, is a steel plate 52 having upwardly projecting points, whereby should it be attempted to drill through the plug 12, the drill, striking the plate 52, would force the container 45 against the points fracturing it and allowing liquid therein to be discharged, through openings 53 in the member 47, into the money compartment 30 therebelow.

In using the safe, air pressure is established in the chamber 11 and th latch member 35 held down by such air pressure is engaged with the latch arm 34 to prevent turning movement of the money compartment30. The space between the money compartment 30 and the liquid chamber 26 is filled preferably with a liquid adapted to dye or stain the content of the money chamber should it be released thereinto, the liquid level being definitely below the open top of the money chamber. The fragile chamber 45, of the locking plug 12, is filled with a similar liquid before being assembled in the plug. Thereafter the plug 12 may be placed and locked, and/or unlocked and removed at will, to permit money or other valuable securities to be protected or to be placed in or removed from the money chamber. Should however, an unauthorized person attempt to drill into, or break open the safe, such action, if through the plug 12, would destroy the fragile chamber 45 and cause the money to be stained and rendered unusable, or otherwise would relieve the air pressure within the chamber 11 allowing the spring 41 to release the latch member 35 and the chamber 30 to be rotated on its trunnions by action of the weight 33. Such rotation would cause liquid in the chamber 26 to overflow into the chamber 30 and deface the contents thereof.

Should it be attempted to attack the safe by heat applied in the vicinity of the plug, melting of the fusible plug 42 would likewise release the pressure in the chamber 11 and cause the same action.

Having described my invention, what I claim 15:

l. A safe, including a pair of shells, one within the other, spaced apart to provide a chamber therebetween adapted to contain a fluid under pressure, a container for liquid within the inner shell, a receptacle for money within said container, and means connected to said chamber and restrained by fluid pressure therein for transferring liquid from said container to said receptacle.
